If the item is crafted at the regular Alchemy Machine, the player must obtain and learn the recipe as well as collect the components of the desired item. Items made at the regular Alchemy Machine can be made anywhere in Haven by opening the recipe tab, which is keybound to F5 by default.

Once the player has collected the required components, the desired item can be transmuted. Certain items must be crafted via specific stations, and in the case of furniture, components must be collected in the treasury of the player's guild instead of the arsenal.

Crafting is not tied to any skill and always succeeds.

Upgrading

UVs will transfer.

UVs will be discarded.

When upgrading an item from one star level to the next, crafting also requires a precursor item. Items related to each other in this way are in the same alchemy path. The precursor item must be unequipped in order to be used in a craft. The upgraded item replaces the precursor item in the player's arsenal.

To upgrade a 3-star item to 4 stars, the 3-star item must be heated to level 5 or higher. To upgrade a 4-star item to 5 stars, the 4-star item must have heat level 10. Beyond these minimum requirements, the heat level of the precursor item has no effect on the quality of the upgrade. The upgraded item always begins at heat level 1.

If the precursor item is bound, then the newly upgraded item will also be bound. Because an item must be equipped to be heated, and equipping an item binds it, this means that any newly made 4- and 5-star item is bound. The item cannot be traded to another player, unless an unbinding fee is paid at Vise.

When upgrading an item with one or more unique variants, the player can choose whether to "Transfer Unique Variants" under the "special" section of the crafting interface. If the UVs are kept, then the upgraded item will have those UVs, with no chance of more or better UVs. If the UVs are discarded, then the upgraded item has a chance of acquiring up to three UVs. This chance is the same as an item made from scratch.

Upgrading preserves accessories, as long as the upgraded version has the accessory slot. If the item does not have a slot for the accessory, then the accessory is destroyed. For example, if an Ash Tail Coat with an aura attached is upgraded to a Skolver Coat then the aura will be destroyed.

Upgrading an item can significantly improve its performance in certain combat situations. The next item must be carefully chosen if the item has a branched alchemy path, and this decision is often influenced by the combat situations the player plans to use the item in. For example, upgrading a Brandish up to the Voltedge is a good choice for some places, but Acheron is better for others. The solution is to plan ahead as well as craft a variety of gear, because the player can obtain more than one Brandish and so on. Upgrading is also integrated into player progression, because higher star items are necessary to receive Star Certification from Barrus in the Hall of Heroes, thus unlocking more opportunities for exploration in deeper depths and higher ranked missions. On the other hand, players might not want to continue upgrading certain items in order to use them in the desired tier of Lockdown.

Economics

Acquiring an item via crafting is almost always significantly less expensive than buying the item from a vendor or the Supply Depot. Crafting also offers a chance of acquiring up to three unique variants, which does not occur when the item is purchased from a vendor or the depot.

A 5-star recipe costs more than its 2-, 3-, and 4-star versions combined. The overall cost of a completed 5-star item dwarfs the entire cost of making a 4-star item from scratch and heating it. In other words, as far as cost is concerned, a typical 4-star item is far less than halfway finished on its way to being a fully heated 5-star form.

There are currently no transmutable 0-star items.

Items crafted via special alchemy stations have built-in recipes and therefore no recipe purchase cost. Many items crafted at these machines have economic patterns similar to items crafted at the standard alchemy machine, frequently differing significantly in total crown cost as well as material quantity.

The following table summarizes the standard crafting costs of most items created via the standard alchemy machine. A few items do not follow these patterns consistently or predictably, such as the Swiftstrike Buckler and Lightning Capacitor.
